CEMEDINE SX720BH AX-218 333ml High-Viscosity Black Flame-Retardant Elastic Adhesive for Electronic Components

CEMEDINE SX720BH Cartridge Adhesive is a high-viscosity black one-component elastic adhesive developed for electrical and electronic component fixing, insulation and waterproof sealing. The AX-218 333ml cartridge provides excellent bead stability, flame-retardant performance and controlled dispensing for professional electronic manufacturing applications.

Product Overview

CEMEDINE SX720BH AX-218 is the 333ml cartridge version of the black high-viscosity SX720BH elastic adhesive. It belongs to CEMEDINE’s SX720 series developed specifically for electrical and electronic equipment.

The product uses an acrylic-modified silicone resin system and cures at room temperature through atmospheric moisture. No separate hardener or mixing process is required, making the adhesive convenient for production lines, equipment assembly and maintenance applications.

With a viscosity of approximately 82 Pa·s at 23°C, SX720BH provides higher bead stability than the standard-viscosity SX720B. Its high-viscosity black paste helps reduce sagging and unwanted flow around components and on vertical surfaces.

The 333ml cartridge format is suitable for controlled application using compatible dispensing guns and production-line dispensing systems.

Key Features and Advantages

High-Viscosity Black Formulation

CEMEDINE SX720BH Cartridge Adhesive has a high-viscosity formulation designed to maintain bead shape before curing. This makes it useful for component reinforcement, vertical application and thicker sealing areas.

UL94 V-0 Flame-Retardant Performance

SX720BH is UL94 V-0 certified for electrical and electronic applications requiring flame-retardant bonding and sealing performance.

One-Component Moisture Cure

The adhesive is supplied ready to use and cures through atmospheric moisture at room temperature. No weighing or mixing is necessary, helping simplify production and minimize preparation errors.

Siloxane-Free Technology

The SX720 series does not contain low-molecular-weight cyclic siloxanes. This is especially useful in electronic and electrical manufacturing environments where contamination and electrical contact reliability are important.

Fast Initial Performance

The adhesive develops initial strength relatively quickly while providing durable elastic performance after curing.

Flexible and Durable Bond

After curing, the material remains elastic and helps absorb vibration, mechanical movement and dimensional changes caused by temperature cycling.

Applications

PCB Component Fixing

CEMEDINE SX720BH Cartridge Adhesive is suitable for fixing capacitors, coils and other components on printed circuit boards.

Its high viscosity helps the applied material remain around components and reduces flow before curing.

Transformer and Power Supply Sealing

SX720BH can be used for insulation sealing around transformers, power supplies and related electrical assemblies.

Electronic Waterproof Sealing

The product is suitable for waterproof sealing around electronic components, electrical housings and cable entry areas where moisture protection is required.

Industrial Electronic Equipment

It can also be applied in industrial control equipment, electrical modules and precision electronic assemblies requiring flame resistance, elasticity and controlled adhesive placement.

Suitable Applications

Typical applications include:

PCB component fixing
Capacitor reinforcement
Coil fixing
Transformer insulation sealing
Power supply sealing
Electronic waterproof sealing
Electrical enclosure sealing
Industrial control modules
Precision electronic equipment
